ABSTRACT 

Background: The taxonomic position of enigmatic pygmy dormouse Typhlomys (Rodentia: Platacanthomyidae) from Vietnam is reconsidered based on both morphology and sequence data. 

Results: The analysis of mitochondrial and nuclear genes has shown that the pygmy dormouse from Lao Cai Province of northern Vietnam belongs to a distinct phylogenetic lineage of Typhlomys. The DNA analysis has demonstrated a strong genetic difference (0.245 to 0.252 for the cytochrome oxidase gene (COI), 0.079 to 0.082 for interphotoreceptor retinoid-binding protein gene (IRBP), and 0.028 for the growth hormone receptor gene (GHR) between this lineage and the sample from South China. Multivariate analysis of cranial and dental data, as well as of some external characters, has also separated the Vietnamese population from the pygmy dormouse from Fujian in southern China, the type locality of Typhlomys cinereus (Bull Soc Philomath Paris 12:8–10, 1877). 

Conclusions: Both genetic and morphological data confirm that there is a second species, Typhlomys chapensis (Field Mus Nat Hist Zool Ser 18:193–339, 1932), in the heretofore monotypic genus Typhlomys.

[Herpetology • 2014] Three New Species of Pseudocalotes (Squamata: Agamidae) from southern Sumatra, Indonesia; Pseudocalotes cybelidermus, P. guttalineatus & P. rhammanotus

Pseudocalotes cybelidermus

Harvey, Hamidy, Kurniawan, Shaney & Smith, 2014

Abstract

We describe three new species of Pseudocalotes from the Bukit Barisan Range of southern Sumatra, Indonesia. Pseudocalotes cybelidermus, P. guttalineatus, and P. rhammanotus differ from most congeners in having serrate dorsal crests that extend to the base of the tail and a dorsolateral series of enlarged heavily keeled scales. In these new species, subdigital lamellae of Toe III have prominent preaxial keels and lack or have greatly reduced postaxial keels. In contrast, P. rhammanotus resembles P. tympanistriga by having bicarinate subdigital lamellae at the base of Toe III. Like most congeners, these new species appear to be restricted to humid forests above 1000 m. We report several new morphological characters for Pseudocalotes and discuss their diagnostic value. Future systematic studies of this genus should assess presence/absence of interparietals, four different kinds of modified scales on the neck, a dorsolateral series of heavily keeled scales, and unicarinate lamellae under the distal phalanges of most fingers and toes. Our comparisons among congeners demonstrate the diagnostic value of width of the gap between the nuchal and dorsal crests and frequency data for contact between the nasal and supralabials and between the postmentals and infralabials. Finally, we discuss variation in morphology of subdigital lamellae at the base of Toe III and describe new conditions intermediate between the serrate fringe of most Indochinese species and the bicarinate lamellae of the P. tympanistriga.

[Herpetology • 2014] Phylogenetic Relationships of Semaphore Geckos (Squamata: Sphaerodactylidae: Pristurus) with an Assessment of the Taxonomy of Pristurus rupestris

Abstract

A molecular phylogeny of the sphaerodactylid geckos of the genus Pristurus is inferred based on an alignment of 1845 base pairs (bp) of concatenated mitochondrial (12S) and nuclear (acm4, cmos, rag1 and rag2) genes for 80 individuals, representing 18 of the 23–26 species, and the three subspecies of P. rupestris. The results indicate that P. rupestris is polyphyletic and includes two highly divergent clades: the eastern clade, found in coastal Iran and throughout the Hajar Mountain range in northern Oman and eastern UAE; and the western clade, distributed from central coastal Oman, through Yemen, Saudi Arabia and north to southern Jordan. Inferred haplotype networks for the four nuclear genes show that the eastern and western clades of “P. rupestris” are highly differentiated and do not share any alleles. Moreover, although the two clades are differentiated by a morphological multivariate analysis, no one character or set of characters was found to be diagnostic. Based on the molecular analysis of specimens from the type locality of P. rupestris rupestris, the name P. rupestris is applied to the eastern clade. The name that should apply to the western clade cannot be clarified until morphological and genetic data for “P. rupestris” is available from the vicinity of Bosaso, Somalia, and therefore we refer to it as Pristurus sp. 1. The phylogenetic tree of Pristurus supports the hypothesis that P. celerrimus is sister to all the other species in the analyses and that the Socotra Archipelago was independently colonized a minimum of two times.

ABSTRACT

Middle Jurassic to Early Cretaceous deposits from northeastern China have yielded varied theropod dinosaurs bearing feathers. Filamentous integumentary structures have also been described in ornithischian dinosaurs, but whether these filaments can be regarded as part of the evolutionary lineage toward feathers remains controversial. Here we describe a new basal neornithischian dinosaur from the Jurassic of Siberia with small scales around the distal hindlimb, larger imbricated scales around the tail, monofilaments around the head and the thorax, and more complex featherlike structures around the humerus, the femur, and the tibia. The discovery of these branched integumentary structures outside theropods suggests that featherlike structures coexisted with scales and were potentially widespread among the entire dinosaur clade; feathers may thus have been present in the earliest dinosaurs.

Abstract

Based on field surveys undertaken between 2010 and 2013, museum studies in Thailand and the UK, and an extensive literature review, this paper provides information on the 28 species and 12 genera of murine rodents currently known from peninsular Myanmar, Thailand and Malaysia and Singapore. It incorporates a detailed summary of past research, 1851–2013, of the Murinae in the study area and includes descriptive characters of the external, cranial and dental morphology and measurements for each of the rodent species. It lists and maps the 93 murine taxa described from the peninsula, 84 of which are currently considered to be synonyms at species level. Each of the 389 different localities on the 28 distribution maps is numbered and linked to its source, either literature or museum specimen, and listed in the online gazetteer. The global conservation status of each species is obtained from the IUCN Red List. Remarks are made, where data are available, on the ecology, karyology, fossil history, sperm morphology, phylogeny, and taxonomic history and ambiguities. Recommendations are made for further research. A series of illustrated matrix keys is provided to assist with the identification of all the murine genera and species within the study area.

Key words: Taxonomy, distribution, identification keys, karyology, ecology, conservation status.

Abstract

 Voeltzkowia is a monophyletic genus of burrowing skinks endemic to Madagascar. The fossorial habits of these species make them hard to see and study, and witness their life history traits. During two herpetological surveys in southwestern Madagascar (in 2009 and 2011) we found several Voeltzkowia rubrocaudata individuals in a corn plantation, a habitat that differs from the forested habitat reported in the literature. Life colouration for this shy scincid is described for the first time.

[Herpetology • 2009] Thamnosophis mavotenda • Phylogenetic Relationships of A New Species of pseudoxyrhophiine Snake (Reptilia: Lamprophiidae) Suggest A Biogeographical Link Between western and northern Madagascar

Thamnosophis mavotenda

Glaw, Nagy, Köhler, Franzen & Vences, 2009

Abstract
We describe a new species of the pseudoxyrhophiine snake genus Thamnosophis from a dry forest of the karstic massif Tsingy de Bemaraha in central western Madagascar. Thamnosophis mavotenda sp. n. is characterised by 19 dorsal scale rows, 188 ventrals, 110 subcaudals, and by colouration (e.g. yellow head sides). Morphological and molecular phylogenetic data indicate that the species is most closely related to the recently described Thamnosophis martae from the far north of the island which inhabits dry karstic forest and subhumid lowland rainforest. This species pair represents a well-supported example of a sister-group relationship in snakes between northern Madagascar and the Tsingy de Bemaraha plateau, and corroborates preliminary observations in other reptile species. We discuss this finding in the light of recent hypotheses on the biogeographic zonation of Madagascar.

Keywords: Serpentes; Pseudoxyrhophiinae; Thamnosophis; New species; Madagascar; Biogeography

Etymology: The specific epithet is derived from the Malagasy words “mavo” (yellow) and “tenda” (throat) and refers to the yellow throat of the holotype. It is to be treated as a noun in apposition for the purposes of nomenclature.

Distribution and Conservation: Thamnosophis mavotenda is only known from a single individual captured in the Tsingy de Bemaraha National Park. Thus, any statements on the species’ distribution and conservation status must remain tentative. Several Malagasy reptile and amphibian species are known only from this nature reserve (e.g. Schimmenti and Jesu 1996; Puente et al. 2005; Glaw et al. 2007a; Köhler et al. 2007), suggesting its importance as a center of endemism. It is therefore possible that T. mavotenda is endemic to the Tsingy de Bemaraha as well. We did not notice any obvious threat to the species, and its occurrence in a relatively large, protected area seems to indicate that it is not severely threatened, although it is remarkable that intensive surveys in this park (Bora et al. in press) did not reveal further specimens. Using the same rationale and IUCN criteria as applied during the Global Amphibian Assessment for Malagasy amphibians (Andreone et al. 2005), we classify T. mavotenda as “Data Deficient”.

[PaleoMammalogy • 2014] “Eodelphis” kabatensis • A New Name for the Oldest True Dolphin Stenella kabatensis Horikawa, 1977 (Cetacea, Odontoceti, Delphinidae), from the upper Miocene of Japan, and the Phylogeny and Paleobiogeography of Delphinoidea

ABSTRACT

The oldest reported fossil record of Delphinidae is from the late Miocene (11 Ma) of California. Reliable Miocene fossil delphinids, however, are few. “Eodelphis” kabatensis from the upper Miocene Mashike Formation (8.5-13.0 Ma), Hokkaido, northern Japan, is the oldest described Miocene delphinid including a skull. Therefore, this species is a significant clue to understanding the early evolutionary history of Delphinidae. The original taxonomic assignment of this species within the genus Stenella is questionable; thus, we propose a new combination for the species, “Eodelphis” kabatensis Horikawa, 1977. Eodelphis is a basal delphinid, and comprehensive morphological cladistic analysis, including molecular topological constraints, supported this taxonomic revision. Paleobiogeographic analyses based on the present morphological cladistic analysis and analysis under the molecular constraints suggest that the origin and early diversification of Delphinidae occurred in the middle Miocene Pacific Ocean or elsewhere, respectively.

CONCLUSIONS

We redescribed the late Miocene delphinid, Stenella kabatensis (8.5–13.0 Ma), from Hokkaido, northern Japan, as a new genus “Eodelphis”. Both a comprehensive morphological cladistic analysis and this analysis under the constraint tree of molecular phylogenetic analyses support a new combination of the species; i.e., Eodelphis is significantly more archaic than the Stenella complex. Those analyses also indicate that the two extinct species Stenella rayi and Tursiops osennae are not included in the Stenella complex. “Eodelphis” is significant for understanding the origin, early evolution, and paleobiogeography of Delphinidae, as well as calibration of the molecular divergence estimates: “Eodelphis” kabatensis is the oldest and only valid Miocene delphinid species yet described. However, paleobiogeographic analyses based on the present phylogenetic analyses suggest different biogeographic scenarios: origin and early diversification in the middle Miocene Pacific Ocean or outside the Pacific Ocean. To resolve the origin of Delphinidae, we need to include more fossil delphinids and kentriodontids in phylogenetic analyses.

Unfortunately as it turns out - Eodelphis  is a preoccupied name for Cretaceous marsupial. So, it will require an additional paper proposing yet another replacement name.

Cyrtodactylus vilaphongi

Schneider, Nguyen, Le, Nophaseud, Bonkowski & Ziegler, 2014

Abstract

We describe a new species of the gekkonid genus Cyrtodactylus on the basis of two specimens collected from limestone forests of Luang Prabang Province, northern Laos. Morphologically, the new species is distinguishable from its congeners by a combination of the following diagnostic characters: maximum SVL 86.1 mm; supralabials 9 or 10; infralabials 7–9; dorsal tubercles in 15 or 16 rows at midbody; ventral scale rows 34–36 at midbody; precloacal groove absent; femoral scales not distinctly enlarged; precloacal pores absent in females (unknown in males); subdigital lamellae under the fourth finger 18 or 19, under the fourth toe 18–20; subcaudals not transversally enlarged; dorsal bands white, 4 or 5 between limb insertions plus another one between hind limbs; tail banded. Based on molecular analyses, the new species is clustered in the same clade with C. wayakonei and two other species from Luang Prabang and Houaphan provinces.

 Pù Hu Bent-toed Gecko | Cyrtodactylus puhuensis

Nguyen, Yang, Thi Le, Nguyen, Orlov, Hoang, Nguyen,
Jin, Rao, Hoang, Che, Murphy & Zhang, 2014

Abstract

Species of bent-toed gecko (Cyrtodactylus) in Vietnam have been described at a rate of nearly four species per year since 2007 mostly based on morphological data. A tool that guides species delimitation will accelerate the rate of documentation, and at a time when the recognition of species greatly benefits conservation. We use DNA barcoding using COI (550 bp) to re-examine the levels of genetic divergence and taxonomic status of 21 described species of Vietnamese bent-toed geckos. Tree-based analyses resolve all sampled species and identify potential undescribed taxa. Kimura 2-parameter genetic distances between the described species average 21.0±4.2% and range from 4.3% to 28.7%. Further, our analyses discover two potentially new species from Vietnam, two from Laos and one from China. Herein we describe the new species Cyrtodactylus puhuensis sp. nov. from Vietnam on the basis of both genetics and morphology. Genetically, it differs from the remaining species by an average K2P distance of 24.0±1.8%. Morphologically, the new species is diagnosed by its medium-size (snout-vent length 79.24 mm and tail length 82.59 mm, for the single known individual), in having a series of moderately enlarged transverse subcaudals and a series of moderately enlarged femoral scales that extend from precloacal scales, in possessing femoral scales without pores, with males having five precloacal pores, and in exhibiting 8 supralabials, 10 infralabials, 23 narrow subdigital lamellae on its fourth toe, and 36 transverse ventrals.
